This plugin allows files to be uploaded to the wiki over the web.
contains html as a web page; including running any malicious javascript
embedded in that page.
-To provide a way to combat these abuses, the wiki admin can specify a
-[[ikiwiki/PageSpec]] on their preferences page, to control what types of
-attachments can be uploaded. The regular [[ikiwiki/PageSpec]] syntax is
-expanded with additional tests.
+If you enable this plugin, be sure to lock it down, via the
+`allowed_attachments` setup file option. This is a special
+[[enhanced_PageSpec|ikiwiki/pagespec/attachment]].
-For example, to limit arbitrary files to 50 kilobtes, but allow
-larger mp3 files to be uploaded, a test like this could be used:
-
- (*.mp3 and maxsize(15mb)) or (!ispage() and maxsize(50kb))
+This plugin will use the [[!cpan File::MimeInfo::Magic]] perl module, if
+available, for mimetype checking.
-The following additional tests are available:
-
-* maxsize(size)
-
- Tests whether the attachment is no larger than the specified size.
- The size defaults to being in bytes, but "kb", "mb", "gb" etc can be
- used to specify the units.
-
-* minsize(size)
-
- Tests whether the attachment is no smaller than the specified size.
-
-* ispage()
-
- Tests whether the attachment will be treated by ikiwiki as a wiki page.
- (Ie, if it has an extension of ".mdwn", or of any other enabled page
- format).
-
- So, if you don't want to allow wiki pages to be uploaded as attachments,
- use `!ispage()` ; if you only want to allow wiki pages to be uploaded
- as attachments, use `ispage()`.
+The `virusfree` [[PageSpec|ikiwiki/pagespec/attachment]] requires that
+ikiwiki be configured with a virus scanner program via the `virus_checker`
+option in the setup file. If using `clamav`, with `clamd`, set it to
+"clamdscan -". Or to use clamav without the `clamd` daemon, you
+could set it to "clamscan -".
